> the rapid advances of AI have altered or closed off entirely a lot of the futures that I would find most interesting.
Opening them up again is a possible creative move. For example 'Dune', a far future where AIs and computers are banned and highly taboo because they caused too much trouble. Or there's alternate paths from the actual past such as steampunk in which we pushed mechanical engines further instead of switching (!) entirely to electronics.
I agree that opening up opportunities for other futures is good, but I don't think Dune was a good example of that even if you like the story -- Dune simply avoided the issue by assuming the future would implausibly turn into the past and that technology would be rejected and medieval feudalism and centralized religious control would return. A better, more plausible, future would show, as is often the case, that the technology we think is so ground-breaking today, just is integrated into daily life and hardly thought about rather than disappearing (which basically never happens).
